Ok so...
I get 2 errors repeatd more or less 4 times:
1.274762] ACPI BIOS Error (bug): Could not resolve symbol [\_SBPCI0.SAT0.SPT4._GTF.DSSP], AE_NOT_FOUND (20190509/psargs-33)
1.286261] Error: Aborting method \_SBPCI0.SAT0.SPT4._GTF due to previous error (AE_NOT_FOUND) (20190509/psparse-531)
I get the following error after it: mdadm: no arrays found in config file or automatically
I just moved to my good desktop pc. it was time to do so. But now i get this. It does not harm but i delays the boot so much! Especially because the error is repeated quite a few times (like 50?), and in the middle there is this: dadm: error opening /dev/md?*: No such file or directory
after this 30-to-60 seconds pain, i get the following:
Gave up waiting for suspend/resume device
Next error:
[ 34.389380] radeon 0000:01:00.0: failed VCE resume (-110).
[ several different nubers, 34.xxxxx onwards for quite a few times] kvm: disabled by bios
And then it boots completely fine
I get the same error after moving my SSD from one laptop to another.
I didn't wait for the 50 messages but rebooted into rescue mode and let it start-up.
I haven't rebooted yet but first thing I'll try is re-installing grub. 
Oh yes, simply enable "kvm" (hardware virtualisation) in the BIOS/firmware.
Edit
Nope no joy ...... it won't install. 
"grub-install: error: /usr/lib/grub/i386-pc/modinfo.sh doesn't exist. Please specify --target or --directory"
And I noticed that the grub being used is not the Elive one but from the AltLinux that's also on the machine. Might be the firmware/BIOS biting me.
Solved
Set "legacy mode" to "uefi mode" first in the bios
On top:
You might want to reconfigure your X:
"sudo dpkg-reconfigure xserver-xorg"
@stoppy98 if the answer solved your problems:
Please set it to "solved" for search emgines. 
Only the first poster can do that.
this is needed? so i can try to implement it for the installed mode in case of... this dmesg message found? 
This is needed because the gpu differs from the one that was in the original machine and requires a different module to be loaded.
It happens a lot to me when I use Clonezilla to clone whole systems on different nachines.
ok we are talking about different things here 
, where I assume that:
- the default install does not need to reconfigure xserver-xorg (if is required, i will add it)
- you said "to use a system in a different machine", this of course (may) requires new / different configurations, and everything is "up to the user on its own risk", elive cannot do anything from here
in fact, even if you move a system to a different machine, it is suggested to reinstall over (upgrade mode), so the installer has a lot of autodetections that takes care to include or remove packages or daemons that are needed / not-needed in that machine, so a lot of things can affect and reinstalling will improve the overall compatibility and correct drivers & settings
